Nanotech Energy has announced the debut of Nanotech EMI Armor Paint & Sheets, graphene powered coatings and films for electromagnetic interference (EMI) and radio frequency interference (RFI) shielding, as well as heat management.
The EMI Shielding line currently contains six products – all of which are said to be highly conductive and provide excellent external EMI/RFI protection while also preventing internal EMI/RFI leaks. The products can be sprayed, brushed, rolled or dip-coated onto various surfaces, such as glass, plastic and metal – depending on the specific product used.
The Nanotech EMI shielding product line is based on the Company's graphene technology and consists of the following:
- Eco Armor Paint & Sheets: A one-part, aqueous conductive paint, designed to attenuate EMI/RFI and dissipate heat for heat management. This product features graphene-based carbon composite that provides significant weight reduction, corrosion protection and reduced cost, while achieving the required protection for the Gigahertz frequency range.
- Elite Armor Paint: A two-part polyurethane conductive paint, with silver-coated copper flakes, that provides the highest attenuation, especially when thin profiles/coatings are required.
- Elite Armor Sheets: A thin, flexible, scratch resistant and lightweight conductive sheet offering superior EMI shielding properties, along with excellent thermal conductivity, mechanical flexibility and structural integrity.
- Ultra Elite Armor Paint & Sheets: have the attributes mirroring Elite Paint and Sheets mentioned above, but with a polyester binder that provides exceptional flexibility. Ultra Elite paint is a one-part spray, that offers processing advantages, along with the ability to coat enclosures with complex geometry. Ultra Elite Sheets are offered in various sizes.
Electromagnetic shielding prevents electromagnetic waves from impacting sensitive electronics. Traditionally this has been achieved through metallic screens or metal enclosures built within the devices. Painting the shielding could ensure a more thorough coverage with the potential of a reduced manufacturing cost. In addition, Nanotech EMI shielding products can also dissipate the heat away from sensitive electronic devices, allowing the regulation of their temperature and preventing thermal shutdown of modern electronics.
In May 2020, Nanotech Energy announced the official close of its Series C round of funding. This round was expected to close at $25 million, yet included an option to allow for an additional $2.5 million for a total of $27.5 million invested.
